该步进电机驱动器又称为EasyDriver，EasyDriver能够为两级步进电机提供大约每相750mA（两极一共1.5A）的驱动。它默认设置为8步细分模式（所以如果你的电机是每圈200步，你使用EasyDriver时默认为每圈1600步），更多细分模式可以通过将MS1或MS2两个接脚接地进行设置。这是一种基于Allegro A3967驱动芯片的细分断路器。对于此设计的完整规格，请查阅A3967的参数表。它的最大每相电流从150mA到750mA。可以采用的最大驱动电压大概是30V，其中包括板载5V的调压器，所以只需要一个电源。质优价廉，这玩意儿只要十几美元，比你自己制作电路板更便宜。步进电机驱动器设计特色：· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping RESOLUTION to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds

ICN6201/02 is a bridge chip which receives MIPI® DSI inputs and sends LVDS outputs. MIPI® DSI supports up to 4 lanes and each lane operates at 1Gbps maximum; the totally maximum input bandwidth is 4Gbps; and the MIPI defined ULPS(ultra-low-power state) is also supported. ICN6201 decodes MIPI® DSI 18bepp RGB666 and 24bpp RGB888 packets.The LVDS output 18 or 24 bits pixel with 25MHz to 154MHz, by VESA or JEIDA format.ICN6201/02 support video RESOLUTION up to FHD (1920x1080) and WUXGA (1920x1200).ICN6201 adopts QFN48 package and ICN6202 adopts QFN40 package

程序功能说明：1、通过STM32的硬件I2C读写控制BH1750光照度传感器模块测量环境光照强度。2、程序通过串口打印输出光照强度值。3、程序将光照强度值在LCD屏上显示。程序注意事项：1、根据BH1750传感器手册可知，在One Time H-RESOLUTION Mode2测量模式下测量光照强度大于会要120ms以上的测量时间，所以程序在发送测量命令以后应该尽量延时120ms以上，否则测量出来的数据不准确。2、在两次测量之间最好加个延时，也就是在第一次测量结束和下次测量命令发出之间加个100ms左右的延时，否则也会出现测量错误的问题。3、在使用FSMC驱动LCD时不能用I2C1，只能用I2C2，或者将I2C1的时钟和引脚重映射。4、测量结果保存在两个字节中的，所以需要作移位处理，具体处理方式可以产考手册和程序。

Simulation can provide a lot of information about what the system is doing. We canadd the effect of different element, like Encoder RESOLUTION, ADC sampling rate, etc and understand how does it affect the system. Another benefit is the possibility to slow down the process, to gain insight on what happens of fast systems or, vice versa, speed up slow process.Because National Instruments is a unique company in the fact the we provide a fullhardware solution couple with a full development platform, we can use this tools in very particular ways For example, it is possible to combine the LabVIEW Control Design and Simulation Module along with the FPGA module to quickly prototype a controller. One of the main benefits of this approach is that there is no need to compile the FPGA code, which allows for a quick algorithm design turnaround and debugging.
